The Lexus RX 450h, the third generation of Lexus’s luxury SUV, introduces the second
generation Lexus Hybrid Drive technology,.
Lexus has drawn on more than a decade of experience in full hybrid powertrain technology
to bring about improvements in every aspect of the vehicle’s Lexus Hybrid Drive system.
As a result, the RX 450h’s real-world efficiency has been significantly improved, with a 10
per cent increase in engine power, a 28 per cent reduction in combined cycle fuel
consumption, a 30 per cent improvement in cold weather fuel efficiency and an unparalleled
reduction in CO2 emissions.
The third-generation model underwent its first significant revisions for 2012, the changes led
by a redesign of the front end that incorporates the trademark Lexus spindle-shaped grille.
Equipment specifications were improved across the board and a new F Sport version was
added to the range – the first time the RX has been offered in Lexus’s sport-themed trim.
As well as sporty styling elements for the exterior and the cabin, the F Sport is equipped with
a lateral damper system for sharper handling and a better ride.
Lexus Hybrid Drive
The RX 450h is a full hybrid, capable of operation in both petrol and electric modes, or in a
combination of both. It combines the fuel efficiency and reduced emissions benefits of a
series hybrid with the acceleration benefits of a parallel hybrid.
It uses a highly efficient V6 petrol engine and two powerful electric motors working in tandem
to provide an ‘intelligent’ four-wheel drive capability.
Total power output is 295bhp (220kW), enabling a top speed of 124mph and nought to
62mph acceleration in 7.8 seconds. Conversely, the RX 450h has a combined cycle figure of
44.8mpg and its CO2 emissions are also remarkably low for a petrol-powered SUV at
145g/km.
The 3.5-litre DOHC petrol engine has been adapted specifically for use in the hybrid
powertrain. It produces a maximum 246bhp (183kW) at 6,000rpm and 317Nm of torque at
4,800rpm, and features three Lexus hybrid ‘firsts’ to optimise the fuel efficiency: Atkinson
Cycle, Cooled Exhaust Gas Recirculation (EGR) and Exhaust Heat Recovery (I).
The hybrid drive system benefits from refinements in drivability through expanded electric
motor maximum torque bands and an AI-SHIFT transmission control strategy to optimise
engine efficiency.
Selectable driving modes, Eco, EV, Snow and, new from 2012, Sport, further improve the
system’s fuel efficiency and driving performance. EV mode allows the car to be driven under
electric power alone, with minimal noise and zero CO2 and NOx exhaust emissions.
Driving Dynamics
The RX 450h was designed specifically to meet the dynamic handling requirements of the
European market. It delivers the high-speed cruising comfort and composure of a premium
saloon, responsive handling and agility on winding roads and, through its electric four-wheel
drive system, stable and tenacious performance.
A double wishbone rear suspension configuration, allied to an increase in wheelbase length
and track width, improves body roll and pitch control. The front suspension has also been
extensively re-engineered, with new shock absorbers, optimised springs, anti-roll bar and
component geometry.
Electronically Controlled Suspension (standard on the Premier model) gives the driver a
choice of four vehicle height settings over a 60mm range and automatically lowers when
travelling at speed to optimise aerodynamic performance, stability and fuel economy.
Design
The 2012 RX 450h underwent significant changes to its front-end design, creating a sharper
and more distinctive look, led by the adoption of a spindle-shaped arrangement of the upper
and lower grilles – a central element in the latest development of Lexus’s L-finesse design
language
The effect is even more pronounced in the F Sport model, which has a deeper, more vertical
front bumper and a dedicated mesh treatment for the upper and lower grilles. All models
gain new-look rear light clusters.
The RX 450h combines the road presence of a premium SUV with the most compact
packaging possible. It is 15mm longer, 40mm wider, 10mm higher and has a wheelbase that
is 25mm longer than its predecessor, increases that have been kept to a minimum in order
to preserve the car’s agility and town-friendly manoeuvrability.
The reduction of panel gaps and the management of airflow under the vehicle combine with
several multi-function aerodynamic elements to minimise turbulence and give the RX 450h a
drag coefficient (Cd) of 0.32.
Inside the vehicle, the cockpit design showcases numerous advanced features. The
dashboard is divided into two distinct zones: an upper Display Zone, which includes the
Head-Up Display and an eight-inch LCD multi-display screen; and a lower Operation Zone,
which contains system controls such as the steering wheel-mounted multi-information switch
and Remote Touch control. For the 2012 model the cabin benefited from a number of small
but telling tweaks to the trim details and the shape and functionality of some of the controls.
Technology
The RX 450h marked the debut of Remote Touch control, an integral part of the Lexus
Navigation System. It operates on the same basic principles as a computer mouse, and is
quick and intuitive to use, with icons presented on the central multi-display screen that give
access to adjust the audio, navigation, ventilation, phone and set-up systems. For 2012 the
system’s operation was further refined to make it even more user-friendly.
The Head-Up Display (F Sport and Premier grades) presents key driving data in the driver’s
line of sight at the base of the windscreen. Information is shown in white for perfect clarity in
all conditions, and includes vehicle speed, turn-by-turn navigation instructions, audio
information and, where fitted, Adaptive Cruise Control and Pre-Crash Safety system status.
A multi-information toggle switch on the steering wheel lets the driver activate and customise
numerous vehicle functions and information systems without taking a hand off the wheel.
The control is linked to a white OLED multi-information display set within the instrument
binnacle.
Other key features include a Smart Entry and Start system, automatic moving of the driver’s
seat and steering wheel for easy entry and exit, dual-speed power windows and a highefficiency dual-zone climate control system.
Lexus builds on its established high standards in in-car hi-fi with three powerful audio
systems for the RX 450h. These include a top-of-the-range 15-speaker Mark Levinson
Premium Surround System that gives perfect 7.1-channel surround sound. Using the
navigation system’s Hard Disc Drive, the audio system has a ‘sound library’ facility that uses
Compact Disc Data Base technology to transfer and store up to 10Gb of music files.
The navigation system, accessed by the Remote Touch control, has a 40Gb HDD capacity,
making it one of the fastest and most accurate on the market. It covers the whole of Europe
and includes traffic information infrastructure and 3D mapping.
Safety
The RX 450h’s Pre-Crash Safety (PCS) system – an option on Premier grade – sets a
benchmark for anticipatory, preventive safety. Operating at speeds above 3mph, it uses a
millimetre-wave radar sensor to detect objects ahead, determines the collision risk and helps
the driver reduce the chances of an accident happening.
If PCS judges a collision to be highly possible, it will alert the driver and, when he or she
begins to brake, it will activate Pre-Crash Brake Assist to supplement the driver’s braking
effort. If the driver does not brake and a collision is inevitable, the Pre-Crash Brake will
automatically apply the brakes to reduce impact speed. The Pre-Crash Seatbelt is also
activated under emergency braking, or if there is a risk of a loss of vehicle stability.
Adaptive Cruise Control (ACC) works in tandem with PCS at speeds between 31 and
106mph (50 to 170km/h), automatically maintaining a selected distance from the vehicle in
front, and returning to the original cruising speed once the road ahead is clear.
Lexus’s Vehicle Dynamics Integrated Management (VDIM) system processes vehicle status
data from sensors located through the car, integrating the function of the ABS, traction
control (TRC), Vehicle Stability Control (VSC) and Electronically Controlled Brakes (ECB)
with the electric power steering, and also co-ordinating control of the Lexus Hybrid Drive and
electric four-wheel drive systems.
LEXUS HYBRID DRIVE

Second generation Lexus Hybrid Drive combines an increase in engine power with a
significant reduction in fuel consumption

World’s lowest fuel consumption and CO2 emissions for a premium SUV

Three firsts for Lexus Hybrid Drive: Atkinson Cycle, Cooled Exhaust Gas
Recirculation (EGR) and Exhaust Heat Recovery (I)

Cold weather operational efficiency improved by 30 per cent

Wider electric motor torque bands give enhanced drivability

New transmission control for optimum engine efficiency

Selectable Eco, EV, Snow and (new for 2012) Sport drive modes, improve hybrid
system fuel efficiency and driving performance
The RX 450h’s Lexus Hybrid Drive System represents a significant development of the
world’s first high-performance, full hybrid drive. Introduced in the RX 400h, this system was
the first to successfully add a true performance dimension to the traditional hybrid
advantages of fuel economy and low emissions, an achievement that revolutionised
powertrain technology in the premium segment.
Lexus has drawn on more than a decade’s experience in full hybrid powertrain technology to
improve in every aspect of its second generation Lexus Hybrid Drive. The result is a marked
increase in engine power, a significant improvement in fuel economy and an unparalleled
reduction in CO2 emissions.
The system’s real-world efficiency has also been comprehensively re-evaluated. It benefits
from substantial improvements in cold weather operational efficiency, perceptible
refinements in driveability thanks to wider maximum torque bands for the electric motor, and
a new transmission control strategy to optimise engine efficiency. Four driving modes, Eco,
EV, Snow and, new for 2012, Sport, further improve fuel efficiency and driving performance.
Second Generation Lexus Hybrid Drive
The RX 450h is a full series/parallel hybrid, capable of operation in both petrol and electric
modes alone, or in a combination of both.
It combines the fuel efficiency and minimal emissions benefits of a series hybrid with the
acceleration benefits of a parallel hybrid, while avoiding any of their respective
disadvantages. As a result, it delivers performance on a par with conventional powerplants
with a larger cubic capacity, while returning fuel consumption and emissions figures
comparable to those of much smaller engines.
It shares the RX 400h’s drivetrain configuration of a series/parallel hybrid system, employing
a highly efficient petrol engine and two powerful electric motors working in tandem to provide
an ‘intelligent’ four-wheel drive capability.
However, comprehensive improvements to every aspect of the Lexus Hybrid Drive system
dramatically improved overall efficiency, realising a 10 per cent increase in engine power
and a 28 per cent reduction in fuel consumption.
Lexus’s long experience in full hybrid technology has been fundamental to achieving these
improvements, most notably in the field of petrol engine efficiency, electrical energy
management and battery technology.
Improvements to the second generation Lexus Hybrid Drive include:

Atkinson combustion cycle for improved fuel economy

Basic engine improvements for increased power and fuel economy

Cooled Exhaust Gas Recirculation (EGR) for improved fuel economy

Exhaust Heat Recovery (I) for improved fuel economy

Reduced hybrid transaxle friction losses for improved fuel economy

AI-SHIFT control (Artificial Intelligence – SHIFT) for improved performance and
drivability

New Power Control Unit for improved performance and fuel economy

Increased front and rear motor torque for improved performance

Eco and EV driving modes for improved fuel economy

Snow driving mode for improved performance and drivability

Sport mode for faster throttle and steering response
Total power output is 295bhp(220kW), enabling a top speed of 124mph and nought to
62mph acceleration in 7.8 seconds. Conversely, the RX 450h has combined cycle fuel
economy of figure of 44.8mpg. CO2 emissions are 145g/km (VED Band F).
Hybrid Drive System Configuration
The full hybrid drive system combines two distinct front and rear driving units, with their
seamless high-speed interaction managed by the power control unit (PCU).
The front drive unit is a series/parallel hybrid system featuring a 3.5-litre V6 petrol engine,
powerful electric motor, generator, high performance battery, power control unit and a power
split device. The power split device uses a planetary gear set to combine and reallocate
power from the engine, electric motors and generator, as required.
The electric motor, generator, power split planetary gear mechanism and motor-speed
reduction gearing are all housed in a single, lightweight, highly compact transmission casing.
This packaging, comparable in size to a conventional gearbox, is fundamental to the
successful installation of the Lexus Hybrid Drive system in a front-engine SUV platform.
The rear unit provides four-wheel drive via a second electric motor. It is mechanically
independent from the front unit and is activated and continuously adjusted by the Vehicle
Dynamics Integrated Management (VDIM) system, working in conjunction with the PCU.
V6 Petrol Engine
The 3.5-litre DOHC petrol engine is adapted for use in the hybrid powertrain. It produces a
maximum 246bhp (183kW) at 6,000rpm and 317Nm of torque at 4,800rpm, and features
three Lexus hybrid ‘firsts’ to optimise fuel efficiency: Atkinson Cycle, Cooled Exhaust Gas
Recirculation (EGR) and Exhaust Heat Recovery (I).
In conventional four-cycle petrol engines, fuel enrichment is sometimes necessary to cool
the exhaust gases to prevent degradation of or damage to the catalytic converters. In an
Atkinson cycle engine the valves close late, delaying compression. This creates a high
expansion ratio for less compression, reducing intake and exhaust energy losses and
converting combustion energy into engine power more effectively. As a result the exhaust
temperature is lower than in conventional engines.
EGR reintroduces precisely metered exhaust gas – cooled from 880°C to 150°C – into the
intake system, further reducing the engine’s operating temperatures and, at the same time,
reducing engine pumping losses through a reduction in intake vacuum pressure.
Together these technologies minimise the situations where fuel enrichment is necessary to
protect the catalytic converter from overheating damage, thereby improving fuel economy
and reducing emissions.
The I system uses exhaust gas heat to warm the engine coolant at start-up. This reduces the
time the engine takes to warm up, allowing it to be shut off earlier for longer electric motoronly operation, particularly in winter. In tests conducted at -5°C, engine shut-off occurs more
than 15 minutes earlier than in the RX 400h. As a result, the RX 450h achieves an increase
of more than 30 per cent in cold weather fuel efficiency compared to its predecessor.
Hybrid Transaxle
At the heart of Lexus Hybrid Drive is a remarkably compact hybrid transaxle, which
incorporates several improvements. The adoption of an oil slinger has reduced oil pump
drive losses; an oil cooler has been fitted; low friction bearings have been installed at key
points; and numerous components have been tuned and re-profiled. These modifications
combine to increase torque capacity and overall transaxle efficiency.
An improved flywheel damper, with a two-stage, torque absorbing damper, absorbs torque
fluctuations and also the shock of engine stop-and-start. This significantly reduces vibration
and noise, notably in urban driving when the engine stops and starts most often.
Artificial intelligence AI-SHIFT control has been adopted for the first time on a hybrid vehicle.
The system determines whether the vehicle is travelling up or downhill by comparing vehicle
speed with accelerator pedal angle. The transmission then selects the appropriate shift
range – from third to sixth – to maintain engine rpm at an optimum speed for either uphill
acceleration or downhill engine braking.
Sequential shift-matic control is also available, by selecting ‘S’ in the transmission shift gate.
In this mode the driver can select any of six speeds to gain more responsive performance, or
to add engine braking assistance.
Electric Motors
Although power from the front and rear electric motors remains the same as it was on the
RX 400h, at 165bhp (123kW) and 67bhp (50kW) respectively, the improved cooling of the
PCU has increased their continuous maximum torque bandwidth. This gives better
performance, particularly from a standing start.
The front and rear motors deliver increased maximum torque of 335Nm and 139Nm from
zero rpm respectively, while the range of the front motor’s maximum torque is extended by
9mph and that of the rear by 22mph.
Power Control Unit
The Power Control Unit is fundamental to the high speed operation of Lexus Hybrid Drive. It
combines several essential functions, including boosting battery voltage from 288 to 650V
DC; converting hybrid battery voltage from DC to AC to power the drive motors; controlling
motor/generator operation; and converting hybrid battery voltage to 14V to supply accessory
power and charge the auxiliary battery.
The PCU is equipped with a new inverter and has been reduced in volume from 30 to 18.2
litres, with weight cut from 30 to 22kg. A more efficient, stacked inverter construction allows
for cooling on both sides and this improved efficiency has helped increase the power density
by 40 per cent. PCU power losses have been reduced by more than 10 per cent to improve
fuel economy.
Changes in the switching frequency of the operation circuit reduce switching losses and so
further improve fuel economy, while higher operation frequencies reduce inverter noise.
DC/DC Converter
In a conventional, non-hybrid vehicle, the auxiliary battery is charged by an alternator.
Because an alternator cannot operate during engine cut-off, a full hybrid vehicle needs an
alternative system. The Lexus Hybrid Drive PCU incorporates a DC/DC converter to reduce
the high voltage of the 288V system battery to 14V, appropriate for supplying power to the
accessory systems and charging the auxiliary battery.
The performance and functions of the RX 450h’s DC/DC converter have been upgraded: the
control method has been revised; an upgraded switching frequency is used; and an
exclusive coolant path is provided, combining a higher power output with a more compact
design.
High Voltage Battery Pack
The three-block battery structure has been carried over from the RX 400h, but it has a more
compact, lightweight design. It is mounted beneath the second row seats, without impeding
their sliding or folding flexibility.
The 288V pack is divided into three packs, each comprising 10 modules of eight cells. The
battery pack, battery monitoring unit, junction block, service plug and three cooling blowers
are housed in a sheet metal case. The blowers distribute air from the cabin through the
structure, using compact but highly efficient and quiet fans.
Lexus Hybrid Drive in Operation
In the course of any journey, Lexus’s full hybrid system will operate in different modes to
maximise overall efficiency. At rest, the engine stops automatically to conserve fuel. Under
conditions of low engine efficiency, such as at start-up or low to mid-range speeds, the
vehicle runs on the electric motor alone, eliminating CO2 and Nox exhaust emissions. In
normal driving conditions, power allocation is constantly adjusted between engine and
electric motor to combine optimum performance with maximum fuel efficiency.
In a feature unique to the RX 450h’s Lexus Hybrid Drive, the rear wheels are driven by a
second electric motor to provide an ‘intelligent’ electric four-wheel drive capability. Controlled
by the Vehicle Dynamics Integrated Management (VDIM), working in conjunction with the
PCU, four-wheel drive is automatically engaged via constantly adjusted front and rear
electric motor torque under hard acceleration (both from standstill and through the gears),
when driving through bends and whenever the front wheels lose traction.
During deceleration and under braking, the engine switches off and both electric motors act
as high-output generators, driven by all four wheels. This regenerative braking system
optimises energy management by recovering kinetic energy that would normally be wasted
as heat as electrical energy for storage in the high performance battery.
The Lexus Hybrid Drive system monitors itself at all speeds for optimum performance and
fuel efficiency with minimum emissions, either running the electric motors in isolation, the
engine in isolation, or a combination of both. Furthermore, the battery power level is
constantly managed via the engine-driven generator, so there is no need for it to be
recharged using an external source.
Four Driving Modes
The fuel efficiency and performance of the RX 450h’s hybrid drive system are further
enhanced by four driving modes: Eco, EV, Snow and Sport.
Linked to an indicator in the speedometer, ECO mode modifies throttle response to driver
inputs for smoother, fuel-efficient driving. The air conditioning load on the engine is reduced
sharply under acceleration, further adding to fuel efficiency.
The RX 450h automatically operates in EV (electric vehicle) mode from start-up and at
speeds up to 25mph, with vehicle range dictated by the level of battery charge. EV mode
can also be activated manually, via the drive mode switch on the steering wheel. In EV mode
the vehicle can be driven around town with minimal noise and zero tailpipe emissions. As the
petrol engine is switched off, EV mode can contribute to an overall reduction in fuel
consumption.
Snow mode helps modulate use of the accelerator pedal and improve vehicle stability when
pulling away on snow or other slippery road surfaces. Pedal inputs are automatically
adjusted to reduce driving torque and minimise wheelspin; should there be any wheelspin,
the rear electric motor engages to improve traction.
Selecting Sport (using the drive mode switch on the steering wheel) modifies the throttle and
electric power steering settings to gain faster responses, and also programmes the Vehicle
Stability Control and traction control for less intrusive operation, letting the driver fully exploit
the car’s dynamic abilities.
The shift to Sport mode is reflected in the ambient illumination of the instrument panel
changing to red.
DRIVING DYNAMICS

Dynamic handling, tuned for the European market

All-new double wishbone rear suspension and optimised front suspension

Electronically controlled, self-levelling four-position air suspension

Electric power steering

Electric four-wheel drive, unique to Lexus

Electronically Controlled Braking (ECB) system for improved feel and maximum
energy regeneration

Comprehensive measures to achieve class-leading NVH performance

Lateral damper system fitted to new F Sport model
The RX 450h was designed to meet the dynamic handling requirements of the European
market. It delivers the high-speed cruising comfort and composure of a premium saloon,
responsive handling and agility on winding roads and, through its electric four-wheel drive
system, stable and tenacious performance.
A new double wishbone rear suspension configuration replaces the strut-type system used
in the RX 400h. Allied to an increase in wheelbase length and track width, this enhances
body roll and pitch control. The front suspension has also been extensively re-engineered,
with new shock absorbers, optimised springs, anti-roll bar and component geometry.
Electronically Controlled Air Suspension (standard on the Premier model) gives the driver a
choice of four vehicle height settings over a 60mm range and automatically lowers when
travelling at speed to optimise aerodynamic performance, stability and fuel economy.
High Rigidity Bodyshell
An all-new bodyshell with high torsional rigidity gives the RX 450h a 20mm increase in
wheelbase and 70mm increase in track compared to the RX 400h. Eighteen or 19-inch
wheels improve stability, reduce body roll and contribute to better NVH performance. The
engine is positioned lower, lowering the vehicle’s centre of gravity and improving overall
vehicle weight distribution.
All-New Double Wishbone Rear Suspension
The RX 400h’s strut-type rear suspension has been replaced with a new trailing arm, double
wishbone configuration that features high-tensile pressed steel components that are
lightweight but highly rigid. The system’s wider arm span and rigid trailing arm and carrier
joints contribute to a high level of agility and stability, while careful attention to packaging,
including locating the springs under the vehicle floor and low, angled shock absorber
mountings, minimises suspension intrusion into the luggage floor. As a result the loadspace
floor width has increased by 150mm.
Dynamic characteristics, such as compliance steer, steering resistance and bump steer have
been given an optimum balance that communicates steering inputs directly to the tyres to
give highly responsive handling. The load input compliance has been tailored by using
oversized, seated-type bushes to reduce harshness and give outstanding ride comfort.
Optimised linear posture under braking has been achieved by improving anti-lift and antisquat ratios, reducing nose dive under braking and rear end squat under acceleration. A
linear toe curve further stabilises sprung weight dynamics, ensuring stable, controlled,
saloon-like cornering with minimum roll.
Front Suspension
The MacPherson strut front suspension has been comprehensively retuned for improved
agility, stability and ride comfort, gaining new shock absorbers and revised geometry,
springs and stabilisers.
The two front springs are inversely wound, compressing in opposite directions to cancel
torsional forces and enhance manoeuvrability. The diameter of the front anti-roll bar has
been increased, improving cornering stability.
Electronically Controlled Air Suspension
The RX 450h Premier is equipped with a newly engineered, electronically controlled air
suspension system. This has a revised construction, combining pneumatic cylinders with
high-capacity shock absorbers to deliver flat and supple ride comfort with superior roadholding.
The system automatically maintains a level vehicle posture, regardless of how many people
or what size load is on board. Four suspension heights are available, selected using a
control switch by the driver’s seat: Normal, High (+30mm), Low (-20mm front, -5mm rear)
and a Loading mode (-30mm), available only when the vehicle is stationary. For
convenience, a second Loading mode switch is located on the side wall of the luggage
compartment, and the function can still be used when the hybrid system is switched off.
Normal mode is automatically selected at vehicle start-up and is suitable for everyday
driving. When travelling at motorway speeds, the system will automatically lower the
suspension to a height equivalent to Low mode to improve aerodynamics, stability and fuel
efficiency.
The front suspension features MacPherson strut air springs with cylinders integrated in the
shock absorbers. The air piston is located off-centre along the axis of the shock absorber, to
reduce load on the shock. The system incorporates a urethane bound topper and flexible
dust cover to protect the diaphragm. By using a multi-leaf linear control valve, damping force
characteristics have been improved, contributing to greater ride comfort, manoeuvrability
and stability. Adding a rebound spring suppresses in-turn bouncing and further reduces roll
angle when cornering.
The rear suspension has an independent shock absorber/air spring layout. The air piston
has a tapered profile for ideal spring characteristics. As at the front, a bound stopper and
flexible dust cover are used.
A system compressor and dryer are incorporated into the right hand side of the rear bumper,
with a double-layer mount ensuring minimal noise and vibration are transmitted into the
cabin. The air in the compressor is dehumidified to prevent the system freezing in cold
weather, with dehumidified air replenishing the system each time the vehicle is lowered. The
drying element has been changed from conventional silica gel to a more effective synthetic
zeolite, which improves air venting performance and reduces the time taken to lower the
vehicle.
An additional low pressure tank is used to lower the vehicle as quickly as possible when
Loading mode is selected. The rate at which high pressure air can be vented is dependent
on the regenerative capacity of the dryer, so in order to increase lowering speed, air from
each cylinder is first sent to the lower pressure tank, then vented at an optimum rate. At this
point air is regenerated in the dryer and released into the atmosphere at a time when vehicle
height is not being adjusted.
Lateral damper system
The RX 450h F Sport, introduced to the range for 2012, is not just about sportier looks, it
also offers sharper driving dynamics thanks to a lateral damper system that increases
stability and improves ride comfort by absorbing small vibrations.
The system, similar to that introduced in the CT 200h F Sport, uses a front lateral damper in
place of the usual fixed bracing between the left and right suspension towers. A second
damper unit is deployed at the rear, connecting each side of the lower back panel. The units
are designed like a monotube suspension damper and adjust in line with changes in the
body rigidity, noise and vibration of their surroundings to give the best possible absorption of
body torsion, flexure and fine vibrations.
Electric Four-Wheel Drive
The RX 450h’s rear wheels are driven by a second motor to provide electric four-wheel drive
under certain driving conditions, improving traction and vehicle stability. Operation is
controlled by the Vehicle Dynamics Integrated Management (VDIM) system, with automatic
engagement via constantly adjusted front and rear electric motor torque under hard
acceleration both from standstill and at any speed, when driving through corners and
whenever the front wheels lose traction.
Electric power steering
Improved rear stability delivered by the new double wishbone rear suspension allows for a
quicker steering ratio to be used than on the RX 400h. Thus the steering gear ratio has been
reduced to 14.8, further improving agility. Electric power steering is fuel efficient, kinder to
the environment and particularly progressive and responsive in operation. Steering weight is
seamlessly adjusted as vehicle speed increases, giving ease of use at parking speeds and
good feel and control and high cruising speeds. In spite of the longer wheelbase and wider
track, the turning radius is unchanged at 5.7m.
A new constant ball-slide intermediate shaft has been developed to improve steering column
rigidity. The constant slide function allows the shaft to adjust its length according to steering
inputs, giving a smoother steering feel.
EPS is simple and compact in its construction, with the motor, reduction gear and torque
sensor integrated in the steering column. As there is no hydraulic fluid to maintain, the
system is more environmentally efficient, with no risk of leaks and no recycling issues.
Conventional hydraulic power steering systems have to run constantly to maintain pressure,
but EPS uses current from the motor to provide assist torque only when needed. This leads
to a significant reduction in energy consumption in driving conditions where little steering
input is required, for example on long motorway journeys. Compared to a conventional
hydraulic system, EPS can potentially deliver a gain of around three per cent in fuel
economy.
In addition to integrated VDIM steering control, the further benefits of EPS include a 30 per
cent reduction in steering flutter, 40 per cent reduction in steering drift and up to three per
cent less CO2 emissions.
The steering wheel itself is a new 382.6mm diameter three-spoke design. The grip cross
section has been revised for added comfort and the hand-stitched leather cover has an
excellent tactile quality. Steering wheel rake can be adjusted through 48mm and reach
through 40mm.
Along with the driver’s seat, the steering wheel is incorporated in the driving position memory
system. Three positions can be programmed or recalled with one touch. An automatic
away/return function makes access to the driver’s seat easy: the system retracts the steering
wheel to its highest and furthest forward position when the engine is switched off, returning it
to the previous memory position when the vehicle is restarted.
Electronically Controlled Braking (ECB) System
Lexus engineers optimised the RX 450h’s braking effectiveness, controllability and rigidity.
The second-generation Electronic Brake Control system has an independent power supply
and works with VDIM to give improved brake pedal feel and linearity, optimum four-wheel
independent
mpressive
distribution,
braking
assistance
and
maximised
energy
regeneration. Ventilated discs are used front and rear, those at the front increased to 328mm
diameter and those at the rear measuring 309mm across. An independent three-plungertype power supply gives quieter operation.
Lexus Hybrid Drive provides all four wheels with regenerative braking during deceleration
and braking, recovering kinetic energy that would normally be lost as heat, as electrical
energy for storage in the system’s high-performance battery.
Noise, Vibration and Harshness (NVH)
Special attention has been paid to reducing NVH levels in the RX 450h’s body structure, to
ensure a calm cabin environment at all vehicle speeds.
Apart from the NVH suppression measures inherent in the refined styling, body structure and
ultra-quiet Lexus Hybrid Drive system, marked improvements in high-speed wind noise
reduction have been achieved by using a three-layer, flush-mounted acoustic glass
windscreen, high-performance weatherstrip door seals and rubber bonnet seals.
Comprehensive use of high-performance soundproofing materials throughout the engine and
passenger compartments has rigorously suppressed road and engine noise. These are
strategically placed to reduce weight and curb sound transmission within the bonnet, fender
seal, instrument panel, outer and inner dashboard surfaces, cabin floor, front and rear
footwells and roof headlining.
Felt-type wheel arch liners further minimise road noise, and additional sound-absorbent
materials have been deployed in the cross-sections of the A, B and C-pillars to reduce noise
transmission through the bodywork.
Three damping braces on the front cowl both improve pedestrian protection and suppress
windscreen vibration. A caulking sponge is applied between the cowl and windscreen which
adds to safety performance and cabin quietness. The underbody is extensively treated with
a highly rigid vibration damping coating, which both reduces weight and ride noise.

The RX 450h showcases numerous advanced features and superb functionality that focuses
on intuitive, user-friendly control operation for both driver and front seat passenger.
The dashboard is divided into an upper Display Zone and lower Operation Zone, which
places all the system controls within easy reach of driver and front passenger.
Remote Touch
Lexus’s Remote Touch, an integral part of the Lexus Navigation System, is a multi-function
device that offers intuitive control of the audio, navigation, climate, phone and vehicle set-up
systems, located immediately in front of the centre console.
It is radically different from remote devices offered by other manufacturers, operating on the
same basic principles as a computer mouse. The adjustable control knob has a good
ergonomic quality, giving the user tactile feedback, and allows the cursor to be moved
quickly across a range of icons on the multi-display screen.
To make it easier to select an icon, the system automatically ‘pulls’ the cursor to an icon if it
passes close to it. This makes the system fast and easy to use, minimising driver distraction
time. The way Remote Touch works was further refined for 2012 to make it even simpler and
more intuitive to use.
Head-Up Display
Using technology that was originally developed for use in fighter jets, the Head-Up Display
(HUD) projects key driving data into the driver’s line of sight at the base of the windscreen,
including speed, navigation commands, audio and (where fitted) Adaptive Cruise Control
and Pre-Crash System status. The system is fitted as standard to F Sport and Premier
models.
Most head-up displays on the market use green-coloured read-outs, with white rejected as a
colour choice because of the blurred effect that can be created against the exterior
background. The white read-outs used by Lexus employ high-intensity LEDs to maintain
clarity and visibility in all driving conditions, tested ahead of production on snow covered
roads.
The display position and lighting intensity can be adjusted and the light level can also be
automatically adjusted in line with ambient lighting conditions.
Lexus Navigation System
The Lexus Navigation System, accessed via the Remote Touch control, has a 40Gb HDD
capacity making it one of the fastest and most accurate systems on the market. It covers all
of Europe and includes access to the traffic information infrastructure of each country.
OLED combination meter
The RX 450h features a white Organic Light Emitting Diode (OLED) multi-information
display. Located between the main instrument meters, it is visible from a wide angle, so the
front passenger can also read information on the screen.
When the driver opens the door, the acrylic panels are activated and light up with increasing
intensity. When the Lexus Hybrid Drive system is switched on, the needles and markings on
the gauges illuminate, followed by the multi-information display. When the driver leaves the
vehicle, this illumination sequence is reversed, gradually fading out the instrumentation
section by section.
Hybrid system indicator
A new hybrid system indicator replaces the tachometer used in previous RX models. As well
as Power and Charge zones, which show system output and regenerative charging, the new
meter has an Eco driving zone and Eco Driving Indicator light. There is also an Eco Driving
Indicator Zone bar graph display, which lets the driver monitor how economically he or she is
driving in real time. Together these three systems increase environmental and fuel efficiency
awareness and promote a driving style that is kinder to the environment. Multi Information
Switch
The multi-information switch on the steering wheel is linked to the multi-information display
and dramatically reduces the driver’s need to use switchgear on the dashboard. This in turn
permits a less cluttered dashboard design. Using a toggle switch, the driver can activate and
customise numerous vehicle functions and information systems without lifting a hand from
the wheel.
The switch offers four modes: Switch, Meter Suggest, User Customised and Cruise
Information.
In Switch mode, the parking sensors, I-AFS headlamps and driving modes can be switched
on or off. In User Customised mode the setting of functions such as the door locks, lights
and meters can be personalised. If, for example, the engine is switched off and a window left
open, the Meter Suggest mode will give an alert. Cruise Information mode lets the driver
switch between different information displays, including average fuel consumption and
estimated driving range.
Smart Entry and Start system
Seamless Anticipation – discreet hospitality that anticipates the user’s needs – is another
principle central to the L-finesse design philosophy and one which can be witnessed in the
smart keyless access to the RX 450h and its sequenced illumination.
As well as phased exterior and interior lighting, the needles, markings and multi-information
display also light up in sequence when the RX is switched on. And when the driver leaves
the vehicle, this illumination sequence is reversed. The instrument binnacle has hybrid blue
lighting.
Easy exit and entry
This discreet hospitality is also evident in the electrically operated driver’s seat, which has an
automatic return and away system, in conjunction with a position memory function. When the
vehicle is switched off, the steering wheel tilts up and forwards to its highest and furthest
forward position and the driver’s seat simultaneously slides back 50mm to make it easy to
get in and out of the vehicle. When the engine is switched on again, they return to their
memory positions.
Dual-speed windows
The dual-speed windows automatically slow at the beginning and end of their opening and
closing sequence, reducing noise and vibration and reinforcing the all-round sense of luxury.
Air conditioning
The RX 450h has automatic air conditioning with independent left and right temperature
control. The system uses a new compressor, a highly efficient heat exchanger and an antivibration condenser mechanism that improves both cooling and heating functions and
reduces operating noise.
The compressor has a humidity sensor that improves system efficiency by taking ambient
humidity level into account, contributing to a 0.8 per cent gain in fuel economy.
Fan and vent noise levels have been substantially reduced and a clean air filter prevents
pollen and dust from entering the cabin. An exhaust gas-detecting recirculation function
automatically switches between fresh and recirculated air modes to maintain good cabin air
quality.
Lexus audio systems
Designed on the principle of “clearer quality through an emphasis on direct sound”, the three
new audio systems for the RX 450h show Lexus building on the exceptional standards it has
already achieved in in-car hi-fi. Every aspect of speaker layout has been re-evaluated. For
example, creative positioning and angling of the tweeters and squawkers perfectly crosschannels sound to the occupant on the opposite side of the vehicle, creating a clear, crisp
acoustic environment.
The entry-level system (SE grade) comprises a six-disc in-dash CD changer, steering wheelmounted controls and nine speakers. DAB-ready, it provides USB and audio jack plug
connections for fully controlled use of portable music players such as iPods, and Bluetooth
mobile phone connectivity with an audio/video streaming function.
A 12-speaker system is also available, with all the above features and the Lexus Navigation
System, fitted as standard to the Luxury and F Sport models. The design includes a tweeter
mounted in each door to give improved sound clarity for the rear seats and surround sound
effects in the front seats, producing a rich, natural feel. In addition, the 20cm sealed box
subwoofer in the rear luggage compartment has an ingenious L-shaped profile to guarantee
adequate volume and achieve deeper, more powerful bass notes.
Mark Levinson Premium Surround System
The top-of-the-range 15-speaker Mark Levinson premium surround sound system (standard
on Premier grade) allows RX owners to enjoy perfect home theatre 7.1-channel surround
sound from selected CDs and DVDs.
The system has several unique features that guarantee unparalleled sound quality. A centre
channel coaxial speaker unit, comprising a 90mm metal cone mid-range and 16mm tweeter,
widens the scope of supported frequencies to produce vocals and instrumentals with a
greater degree of precision than that of a conventional system, while also matching
harmonics between the front right and left channels.
A 200mm Mark Levinson subwoofer in a 19-litre enclosure is independently powered by a
100-Watt Mark Levinson amplifier, allowing it to produce extremely deep bass and sound
effects with ease.
A 65mm Mark Levinson speaker is built into each D-pillar to provide the appropriate right
and left sound channels. Sound diffusion has been optimised so that everyone on board can
enjoy the same audio quality.
In Car Entertainment (ICE) package
For further entertainment options when on the move, RX 450h is available with an optional
ICE package comprising two tablets securely mounted to the rear seatback of the front
seats. Each tablet comprises an eight-inch WVGA screen, integrated DVD player, USB 2.0
reader and SD card reader. The screens operate independently of each other, so one
passenger can watch a disc while the other plays computer games.
The package includes two pairs of infra-red headphones, sized so that they will comfortably
fit young children, plus a remote control. The USB 2.0 connection and SD card reader allow
video clips, music and photos to be viewed from a memory stick or card.
It is available as an option on all grades.
Side and Rear View Parking Monitors
A new Side Monitor makes its debut in the RX 450h, in addition to the Rear View and
Parking Assist monitors.
The system, fitted to the Premier model, uses Charged Coupled Device (CDD) cameras built
into the passenger door mirror and the rear of the vehicle, which work in conjunction with the
front and rear parking sensors to give a view of areas around the vehicle that are difficult to
see from the driver’s seat. Real-time images are shown on either the central display (on
models equipped with the Lexus Navigation System), or the interior rear-view mirror. For
added security, the door mirror camera will continue to work even if the mirrors are folded
back when negotiating a narrow space.
DESIGN

Latest expression of Lexus’s L-finesse design language

New front-end design for 2012 with spindle-shape front grille arrangement

New vehicle architecture with Crossover cockpit design

Advanced packaging for more interior space and improved seat design
Exterior design
The RX 450h combines the road presence of a crossover with the most compact packaging
possible. It is 15mm longer, 40mm wider, 10mm higher and has a wheelbase that is 25mm
longer than its predecessor, but these increases have been kept to a minimum in order to
preserve the car’s agility and town-friendly manoeuvrability. RX maintains its 5.7m turning
circle.
Styling changes for 2012 are led by spindle-shaped arrangement of the upper and lower
front grilles that is a central element in new Lexus design, as also seen in the fourthgeneration GS saloon and the multi-award winning LF-LC concept coupe. The effect is to
give RX 450h a much stronger and individual street presence, a character that is even more
pronounced in the new F Sport model. This has a deeper, more vertical front bumper and a
dedicated mesh treatment for the upper and lower grilles, which together make the new
spindle grille shape an even stronger feature.
The cab-forward silhouette preserves the classic look of a crossover, while the clear axis of
the shoulder and distinct crease along the C-pillar form a new architectural framework. The
pronounced wheel arches flow seamlessly into both bumper and doors, and the vehicle’s
taut rear corners are emphasised by the smooth integration of the bumper.
Distinctive side window mouldings adopt the L-finesse arrowhead shape, following a subtly
concave line across the A and C-pillars before extending at either end. The plated door base
mouldings increase in thickness towards the rear of the vehicle, giving a sense of strength
and lowered centre of gravity.
Aerodynamic multi-function design elements
The reduction of panel gaps and the management of airflow under the vehicle combine with
several multi-function aerodynamic elements to minimise turbulence and give the RX 450h a
class leading drag coefficient (Cd) of 0.32.
These elements include highly sculpted door handles with a touch sensor smart switch in
place of a button release on the front doors. The large, multi-function door mirrors also have
a sculpted appearance, combining a rounded upper surface with a cut-away lower surface.
This new design reduces wind noise by 20 per cent compared to those on the previous RX.
The mirrors incorporate LED turn indicators that also function puddle lights and, where
specified, a parking camera on the passenger side.
The rear wiper is concealed beneath the spoiler, which has a blacked-out underside to give
a sleek appearance. As well helping reduce the vehicle’s Cd value, it also houses a highmounted stop lamp and radio antenna.
Hybrid-exclusive Design Features
A number of exterior design details identify the RX 450h as a Lexus hybrid model. At the
front, the grille has a blue-tinted Lexus emblem and the bumper is reworked to include an
extra intake. The headlamp clusters are also blue-tinted. To the side there are blue scuff
plates and a hybrid logo and at the rear the lamp clusters are again shaded blue and there is
further hybrid badging.
Interior design
Interior width has been increased by 52mm between the armrests, the front-to-rear couple
distance is 10mm longer, and the length of the boot space is 10mm longer, compared to the
RX 400h. This contributes to a spacious and comfortable cabin environment.
Dual-zone cockpit
The cockpit design addresses the need for drivers to take in a lot of visual information
without losing attention on the road ahead.
The space is divided into two distinct zones: an upper Display Zone, which combines a
head-up display (F Sport and Premier grades) with an eight-inch colour LCD multi-display
screen, and a lower Operation Zone, which gives access to controls such as the multiinformation switch on the steering wheel and Remote Touch. All functions are arranged so
that they can be operated by both driver and front seat passenger.
Seating
The full-leather, electrically adjustable front seats are more comfortable thanks to increased
backrest height and width and cushion thickness and width. Electric cushion length
adjustment is included in the 10-way seat control for the front seat in the RX 450h Premier.
New heaters provide heat at different temperatures across different parts of the seat.
The rear seats maintain the proven 40:20:40 split-folding configuration, which offers more
flexibility and practicality than the usual 60:40 format. The seats can be slid forwards and
backwards to increase legroom or luggage capacity, and can also be reclined.
Storage and Luggage Compartment
The interior is designed to provide flexible and practical storage space. There are numerous
compartments, including cup, coin and card holders; various trays; a locking glove box;
capacious front and rear door pockets; an overhead console; and a multi-compartment
centre console, which has 12V power outlets and is large enough to store the owner’s
manual and provide an additional 21 litres of space.
The adoption of a double wishbone rear suspension design reduces the degree of intrusion
into the luggage compartment, increasing loadspace floor width by 150mm and overall
volume to 446 litres. New levers are located on the side wall of the load area to enable
remote one-touch folding of he rear seats. Models fitted with air suspension also have a
vehicle height switch on the side wall for easy adjustment when loading or unloading.
Colours and Trims
The RX 450h is available in nine exterior colours: Starfire Pearl, Mercury Grey, Velvet Black,
Celestial Black, Vanilla Mist, Burgundy Red, Atlantic Blue, Satin Silver and Sienna Brown.
Interior trim choices are ivory, light grey, saddle tan or black leather (high quality semi-aniline
leather on Premier grade) with dark grey gloss trim. Black leather is standard on the F Sport
model. An optional Wood Pack providing wood trim inserts and a wood-trimmed steering
wheel, is available for Luxury and Premier grades, the latter including a heated steering
wheel.
SAFETY

Advanced active, passive and preventive safety technology

Optional Pre-Crash Safety and Adaptive Cruise Control systems

Vehicle Dynamics Integrated Management (VDIM) for seamless integration of
braking, drive and handling systems

High rigidity bodyshell with 42 per cent high tensile sheet steel content

Excellent pedestrian impact protection

10 airbags featuring award-winning technology
The RX 450h sets high standards for active, passive and preventive safety with
mpressive
body strength, award-winning safety innovations and driver support systems.
Lexus aims to offer a maximum content of safety features that are effective in real-world
situations. It performed 233 crash tests during the vehicle’s development, data from which
helped produce a range of advanced safety technology that redefines occupant protection
through unprecedented synergies between driver intent and vehicle response.
ACTIVE SAFETY
The dual-zone cockpit design provides excellent ergonomics and maximum instrument
clarity, helping drivers to concentrate on the road ahead. The head-up display combines with
the multi-information screen to keep all essential data within the driver’s field of view, and a
multi-information switch lets the driver monitor vehicle information while keeping both hands
safely on the wheel.
For safer night driving, the Intelligent Adaptive Front-lighting System (I-AFS) works in
conjunction with the low beams of the LED headlamps and both the high and low beams of
High-Intensity Discharge (HID) headlamps. When entering a corner, the system calculates
where the vehicle will be in three seconds’ time, based on vehicle speed and steering angle,
adjusting the lateral aim of the lamps accordingly.
Pre-Crash Safety System
The RX 450h’s Pre-Crash Safety (PCS) system (an option for the Premier grade) sets a
benchmark for anticipatory, preventive safety. Operating at speeds above 3mph, it uses a
millimetre-wave radar sensor to detect objects ahead, determines the collision risk and helps
the driver reduce the chances of an accident happening.
If PCS judges a collision to be highly possible, it will alert the driver and when he or she
begins to brake, it will activate Pre-Crash Brake Assist to supplement the driver’s braking
effort. If the driver does not brake and a collision is inevitable, the Pre-Crash Brake will
automatically apply the brakes to reduce impact speed. The Pre-Crash seatbelt is also
activated under emergency braking, or if there is a risk of a loss of vehicle stability.
Adaptative Cruise Control
Adaptive Cruise Control (ACC) works in tandem with PCS at speeds between 31 and
106mph (50 to 170km/h), and forms part of the combined option offered on the Premier
grade. ACC automatically maintains a pre-set distance from the vehicle in front, returning to
the original cruising speed once the road ahead is clear.
Hill Start Assist Control
The RX 450h also features Hill-start Assist Control (HAC), which functions both when driving
forwards and reversing. HAC briefly maintains brake pressure as the driver moves his or her
foot from the brake to the accelerator, to prevent the vehicle from rolling backwards on an
incline. Because the system requires less accelerator input, it reduces wheelspin and gives
smoother pulling-away performance.
Vehicle Dynamics Integrated Management
Lexus’s Vehicle Dynamics Integrated Management (VDIM) system processes vehicle status
data from sensors located throughout the car, integrating the function of the ABS, Traction
Control (TRC), Vehicle Stability Control (VSC) and Electronically Controlled Brakes (ECB)
with the electric power steering, and also co-ordinating control of the Lexus Hybrid Drive and
electric four-wheel drive systems.
Through its integrated control of all the elements relating to vehicle movement, including
motor torque, brakes and steering, VDIM not only optimises activation of braking, stability
and traction control systems, it further improves the vehicle’s overall dynamic performance.
For example, when braking on a surface with unequal grip, VDIM automatically counteracts
the different left and right-side braking forces to maintain straight-line braking. In the event of
under or oversteer, VDIM seamlessly combines engine output and braking control to
stabilise the vehicle.
Moreover, via the EPS actuator, VDIM will augment VSC operation by providing steering
assistance to reduce torque steer under braking on surfaces with varying grip. It will also
introduce steering torque assistance in under and oversteer conditions to help the driver
optimise the front wheel steering angle and maintain vehicle stability with minimum input.
PASSIVE SAFETY
The RX 450h has been engineered with the express aim of achieving the highest safety
performance in terms of full-frontal, offset, side and rear collisions. Beyond securing the
safety of its occupants, it has been designed and rigorously tested for optimum collision
compatibility with vehicles of varying height and weight, and class-leading pedestrian impact
protection.
Forty-two per cent of the body mass comprises high tensile sheet steel, which combines light
weight with very high rigidity. In the event of a collision, impact energy is absorbed by the
front side members, then dispersed through the floor members, doors and pillars.
A wing bracket structure provides rigidity with effective absorption of collision impact energy.
The wing brackets and radiator support upper brackets are designed with bend points to
optimise their impact absorbing efficiency, and the heights of both the wing and bracket have
been calculated to create a structure that will deliver effective energy absorption.
A-pillar reinforcements have been increased with inner reinforcement extended rearwards.
This has increased buckling strength and improved load sustainability when buckled,
restricting deformation of the body around the A-pillars.
The inside of the B-pillars, rails and rocker panels have been reinforced with high tensile
sheet steel, while cross-member reinforcement in the roof, roof header and floor provides
further protection against cabin structure deformation.
Pedestrian Impact Protection
The RX 450h features an impact-absorbing bonnet with a longitudinal frame structure with
excellent energy absorption characteristics, achieving the highest level of pedestrian impact
protection in the premium SUV segment.
The strength of the bonnet lock reinforcement has been optimised through pitch
reinforcement and lightening holes. An ample crush stroke has been incorporated, further
improving protection while maintaining dent resistance and quiet closing quality.
Ten Airbags
The RX 450h is equipped with 10 airbags, including knee airbags for both front seat
occupants, front and rear side airbags and full length curtain shield airbags. The front
passenger is protected by a dual-stage, twin-chamber airbag, shaped like a baseball
catcher’s glove to safely cradle the face and shoulders. This innovation won a breakthrough
technology award in the USA.
Active Headrests and Rear Occupant Protection
Active headrests add to the protection provided for driver and front passenger. In the event
of a rear collision, the occupant’s lower back presses on a mechanism built into the
seatback, popping the headrest up and moving it forwards. This closes the distance between
the person and headrest, minimising the risk of whiplash.
The rear seats are equipped with seatbelt fastening reminders, pretensioners and force
limiters.

Clean and Silent assembly initiatives with Set Part System production line techniques
The RX 450h is built at Toyota Motor Kyushu, where, in 2008, the Kokura plant started
operations as the world first factory dedicated to hybrid unit production. The plant maintains
the highest standards of manufacturing quality by combining innovative production quality
with the skills of takumi – the Lexus master craftsmen.
Each of these elements alone is indispensable, but TMK is pursuing a synergy of the two
through computerisation of master craftsmanship. By programming the sophisticated
processing abilities of the skilled technicians into robots, even higher production precision is
achieved. Other technologies under development include programming the takumi’s sensory
perceptions into measuring devices.
TMK is committed to reducing inconsistencies throughout the RX 450h production line. In
each process, from stamping, painting and assembly, through to inspection, precise data are
measured collated and managed. Measurements for each vehicle are recorded in its
individual production history. By monitoring measurements in real-time, any inconsistencies
or abnormalities can be instantly detected. Cross-checked against design parameters, this
information is then used to hone assembly operations to achieve even greater precision.
Although robots, digital devices and testing equipment are used for many of the tasks and
inspections in the RX 450h assembly process, there are still many areas of manufacturing
where human skills exceed even those of the most sophisticated automated systems. TMK
acknowledges this by integrating Lexus manufacturing quality with a human focus on
subliminal quality; those aspects of a car which cannot be measured or quantified
mechanically, but which are fundamental to achieving the highest levels of perceived quality.
For instance, skilled technicians are able to spot subtle imperfections that are undetectable
by machines, such as small scratches, dull surface patches and gaps or misaligned panels,
and meticulously put them right, one vehicle at a time.
Stamping
Thorough maintenance of the stamping dies is essential to the creation of a flawless
bodyshell. In the stamping process, high pressure is applied to a sheet of steel sandwiched
between top and bottom dies to form various body panels. If dust or other airborne particles
adhere to the die surface, they can leave scratches on the panels that would be difficult to
repair later in the production process. A dust particle need only measure 20 microns – about
the size of a grain of pollen – to have an adverse affect on stamping quality, so stringent
controls are essential to keep dust away from the stamping line.
Twice a week the dies are sanded and washed at a dedicated maintenance area. This
process generates large amounts of dust and to ensure this does not get into the stamping
shop, the maintenance area is surrounded by a three-metre high net – nicknamed Niagara –
across which there is a constant flow of water to catch any airborne particles. Using this net
has reduced the level of airborne particles by more than 90 per cent, resulting in a significant
improvement in the quality of stamped panels.
Bodyshell
The RX 450h’s driving performance, ride comfort and quietness are underpinned by a high
degree of body rigidity, a quality achieved through developments in high-precision advanced
welding technologies.
The bodyshells are created by the spot welding of around 300 stamped parts at 4,000 to
5,000 different points. The welding is performed by robots moving in and around the vehicle
body as it is held in place by a series of jigs. The rigidity and precision of the body is
determined by the number of spots the robots can reach and weld.
The process for the RX 450h marks a substantial increase in the number of weld points,
achieved by introducing new slim robots between the standard units. For example, in the
floor and side panel tack welding process, 14 robots previously made spot welds at 70 to 80
points. Adding slim robots into this task has more than doubled the number of weld points.
Careful analysis ensures the most appropriate number of welds is used for each area, not
only improving body rigidity, but also sharply reducing inconsistencies in bodyshell precision.
Gaps between body panels, as well as the alignment of the body and lamps, are measured
on the production line with precision digital callipers. The measurements are displayed on a
monitor beside the line and the vehicle body cannot proceed to the next stage until all
measurement results are within the required parameters.
Painting
The unparalleled surface quality of the Lexus multi-coat painting process is the product of
lengthy research in coating materials and methods. Depending on the chosen colour, the
number of coats and the properties of the paint used can be changed to achieve shades and
depths of colour that are unique to Lexus.
High quality is also achieved through meticulous cleanliness in the application process,
particularly in the topcoating booths in the latter stages. Eradication of airborne particles is
crucial to successful paint application. Conventional environmental control methods focused
on preventing contamination at the entry and exit points to the booth, using air intake and
discharge equipment. TMK has introduced a system like those used in semi-conductor
factories, using a number of small, one-way air outlets to pressurise the area prior to the
topcoat booth, so forcing air away from it. This approach has yielded a significant reduction
in the infiltration of airborne particles.
To prevent water leaks and rusting, the painting process involves sealing all body seams
before intermediate coat application. Lexus’s legendary attention to detail runs to applying
sealant even to areas that are rarely seen by owners, such as inside the engine
compartment and doors and beneath load space and cabin floors.
To maintain an outstanding surface quality throughout the finishing process, the production
line combines the latest robotised technology with hand polishing by master craftsmen.
Vertical surfaces are water polished with a plane sander after the intermediate coat is
applied, and checked both by eye and digitally.
Hybrid Unit
TMK is the world’s only dedicated hybrid manufacturing facility, designed to provide the
perfect environment for making hybrid components.
Once again, minimising contamination by fine airborne particles is of paramount importance.
This is achieved by atmospheric pressure control, a measure helped by the building’s low
ceiling design.
Introducing positive air pressure inside the plant means air is constantly being forced outside
the building, helping prevent airborne particles from entering. Inside, air pressure is
modulated between different areas to create an air flow in the opposite direction to the
manufacturing sequence. Components are conveyed to downstream processes on shuttered
conveyor routes; the further downstream the process, the higher the air pressure becomes,
with maximum pressure reached in the assembly process itself.
Temperature and humidity are also rigorously monitored to maximise the stability of the
manufacturing environment all year round.
Double measures are in place at the shipping exit to prevent any foreign matter from
infiltrating the plant. The loading dock is completely enclosed and a conveyor transports
parts to the receiving door via an airlock. The personnel entrance is also subject to strict
entry and exit controls. Workers must wear pocketless, anti-static clothing and wash their
shoes. They are also prohibited from bringing in any metal items with them.
Assembly
Numerous ‘clean and silent’ initiatives are being undertaken in all TMK plants. Using a
friction-driven conveyance system in the assembly process is a key contributor to a quiet
factory environment. The conventional chain-driven conveyor has been replaced by a
system that uses urethane rollers to move bodyshells along the assembly line; as well as
being quieter, this consumes less energy and is easier to maintain.
The resultant dramatic reduction in noise improves technicians’ concentration, leading to
improved work efficiency and precision. It also helps the technicians hear more clearly the
sound their tools are making, and the sounds made when fitting connectors, which
encourages greater quality and accuracy. Conversely, noises that may indicate problems are
easier to discern.
Air tools that are typically used for engine and underbody mounting processes have been
replaced with electric nut runners, which give greater precision. Air tool technicians judge
part tightening by changes in sound and vibration, but electric nut runners automatically
adjust to a pre-set torque to give consistent precision and enhance body rigidity. The electric
tools are also quieter and vibrate less.
The RX 450h assembly process involves fitting several thousand parts to the bodyshell.
Traditionally technicians collect components for fitting from racks alongside the line. By
adopting the Set Part System (SPS), Lexus has eliminated the problems associated with
picking the wrong parts and reduced the amount of walking necessary, thereby increasing
working efficiency.
With SPS, all parts required for the assembly travel along the line with the vehicle. Time
spent collecting parts is minimised and the system can respond flexibly to complex part
combinations. SPS has evolved further in the RX 450h door assembly line, where a gondolatype parts conveyance rack has been introduced. On a sub-line, a technician fills the
gondola with the parts needed for one door, after which the gondola merges with the main
assembly line, travelling along with the door to which the parts are to be fitted.
Inspection
Cutting-edge measuring technology is again combined with the skills of the takumi in the
meticulous inspection process. Technicians conduct automated in-line measurements and
quality gate checks throughout the body welding and assembly processes. Checks carried
out at earlier stages are followed by a final fitting inspection in which panel gaps and
alignment are checked by hand and eye. The inspectors who do this work undergo daily
training and testing to maintain their skills levels.
In a unique door closing speed inspection, the inspector closes all doors at a gentle speed to
ensure they close firmly. The speed of closing is set at a maximum 1.2m per second and
monitored by laser equipment. This speed is the equivalent of gently pushing the door with
the fingertips. Lexus build precision ensures the doors can be closed firmly, even with such
light pressure.
After comprehensive road testing, every RX 450h is transferred to a shower test booth to be
checked for leaks. This booth simulates rainfall of 200mm per hour, with water stirred to
replicate storm conditions. Even a severe typhoon generates no more than 100 to 150mm of
rainfall an hour, so Lexus can be confident the vehicle will not leak in even the most severe
weather conditions.

airbags, HID headlamps, rear parking monitor and automatic windscreen wipers. The Lexus

Lexus’s Pre-Crash Safety system and Adaptive Cruise Control, sunroof, and Head-Up
Display, with the Wood Package optionally available.
F Sport grade
The RX 450h adopts a whole new sporty persona with the introduction of an F Sport version
to the RX range for the first time, offering both sharper looks and performance.
Style-wise the F Sport stands out with a deeper, more vertical front bumper and a dedicated
mesh treatment for the upper and lower grilles, which together make the new spindle grille
shape an even stronger feature.
There are also dark-finish 19-inch alloy wheels and F Sport badging on the exterior, while in
the cabin the model’s distinctly sporting character is reflected in aluminium-effect sports
pedals and trim inserts, F Sport smooth leather upholstery and scuff plates with the Lexus
logo in black. There is also a black roof lining and a bespoke steering wheel with a stitched
leather trim.
Other equipment features include a head-up display, and LED headlights with the I-AFS
adaptive system that angles the light beam in line with the vehicle turning angle through
bends and at junctions.
RX 450h Advance
Lexus has enhanced the RX 450h range with the introduction of Advance feature models.
Details and specifications of the current Advance, available since August 2014, can be found
here.
Accessory packs
RX customers can take advantage of accessory packs for the vehicle designed for
practicality and an even greater choice of on-board entertainment.
The Protection Pack provides a strong, woven nylon luggage net, a boot liner with an antislip surface, tailored rubber floor mates, mud flaps and a bumper protection plate.
Lexus’s Entertainment Pack range offers a choice of screen and connectivity options that
lets customers design a system that best suits their needs.
Seatback-mounted holders are available for either iPads or DVD players. The DVD systems
can play the same content on both screens, or run independently for watching movies,
viewing photographs or playing games.
Each pack comes with twin, integrated docks, even if only a single product (DVD player or
iPad holder) is ordered. This means the system can easily be expanded in the future. The
design of the docks reflects the premium quality of the RX’s interior, with all wires concealed
from wire. Customer can use their own headphones, or purchase additional infra-red
headsets to supplement their choice of Entertainment Pack.
A towing pack is available, with a choice of seven or 13-pin electrical wiring kit. When not in
use, the towing hitch can be removed. The towing capacity of the RX 450h is 2,000kg
(braked) or 750kg (unbraked).
